Hi there

I made the edit primarily because someone deleted the road completely as if it didn't exist when really it was just under long term closure. It looked more like a mistake than a road closure so luckily I did my research before just readding it blindly.

I gave the first link a skim, and to me it says it opens on the 27th of this month, which will be a few weeks. Either way in fairness, it's possible the bus company might be slow to catch on.

I'm not local to Milton Keynes, and by the sounds of it neither are you, but if you're confident it's reopened then feel free to change highway=construction to trunk and delete the construction tag.

Cheers,
Sam

Disagree. Looks totally normal to me. It's obviously not quite expressway/motorway sized but everywhere else in the world, mapping this as primary links is normal, as it separates all the turn movements into their own roads. I can find many examples if you want, with this type of interchange. Additionally for ramp exits it's normal to tag highway=motorway_junction

The speed does increase from 50 to 70 at the north of this section and most notably, this section relies on ramps rather than traffic lights. If you prefer, you might consider tagging something like access_control for this instead of expressway. But personally I think the ramps constitute expressway-type design features for this section of road, which isn't necessarily the same kind of high-speed design as a motorway, just limited access and faster than most normal roads.

I'd be very surprised if they didn't repave it again in the foreseeable future, even if the council wasn't saying they expect it to reopen in September.

I definitely think it should remain as highway=construction with that in mind, plus the likelihood of there being other subsurface infrastructure there, and the unlikelihood they would use the corridor for anything but a road. Also, this will prevent lazy people from re-adding the road as if it were open, without checking - seeing a big gap in the road is an immediate red flag.

Painted mini roundabouts should be mapped using a highway=mini_roundabout node and not a circular way. Additionally, all roundabout ways should be tagged junction=roundabout and not oneway=yes.

It's not correct to remove a road completely when it's closed or under construction. According to the council it is expected to reopen in September. As such I've readded the section as being under construction (see https://www.milton-keynes.gov.uk/news/2023/part-a509-be-closed-monday-25-september-2023 )

Cool, good to hear, and no worries :)
